Disc film
Kodak introduced disc film in 1982. This uncommon film format came in the form of flat disc fully housed within in a plastic cartridge. Each disc holds fifteen 10 x 8 mm exposures, arranged around the outside of the disc – very small in comparison with the much more common 35mm film format.
But because the disc film produced photo prints of disappointing quality, it was discontinued and disappeared from the market again just six years after it arrived.
